Bottom Line: At week 6, half the group were supplied daily kiwifruit for 3 weeks with cross over at week 9 until week 12.Compared to baseline, lipid, glucose, insulin and AOA measurements were improved at 12 and 52 weeks.Body measurements did not change.

ABSTRACT
We examined the effect of a 9-week diet and physical activity intervention provided in the workplace by a group education session where personal dietary and physical activity goals were proposed. Measurements of anthropometry, fasting blood lipids, glucose and insulin, assays for antioxidant activity (AOA) and questionnaires were completed at 0, 3, 6, 9, and 12 weeks in 50 healthy workers (50% male, mean age 46y). Followup measurements in 39 (56% male) were possible at 52 weeks. At week 3 a group dietary and physical activity "motivational seminar" was held. At week 6, half the group were supplied daily kiwifruit for 3 weeks with cross over at week 9 until week 12. Compared to baseline, lipid, glucose, insulin and AOA measurements were improved at 12 and 52 weeks. Body measurements did not change. Group diet and physical activity advice reinforced over 9 weeks is associated with a sustained improvement in cardiovascular risk factors at 52 weeks.

fig2: Measurements of total cholesterol (open diamond), LDL cholesterol (closed circle), the ratio of total to HDL cholesterol (open circle) and HDL cholesterol (closed triangle) over 52 weeks in 39 volunteers. Data are mean ± SEM.

Mentions: In the 39 subjects (22 M, 17 F) who were measured at 52 weeks, there were no changes in anthropometric data but systolic blood pressure increased from baseline (Table 3). The 4 mmHg increase is probably not clinically meaningful. Favourable blood lipid changes seen over the 12 weeks persisted at 52 weeks (Figure 2 and Table 4); glucose and insulin decreased significantly and insulin sensitivity increased. Insulin in males was maintained (week 0, 56 ± 28; week 52, 55 ± 29 pmol/L, P = .87) but decreased in females (week 0, 66 ± 34; week 52, 49 ± 27 pmol/L, P < .0001) and insulin sensitivity increased in females only (P < .001). AOA increased, particularly in those who had an initial level less than 1200 μmol/L.
